In this episode of DIY or Buy I will be showing you how I created my own launchpad. That means I will show you how I combined a design idea with 3D Prints, WS2812 LEDs, tactile switches and an Arduino to create a proper MIDI instrument. While building I will also tell you a bit about a keyboard matrix and in the end determine what advantages the DIY Launchpad offers. Let's get started!
Step 1: Watch the Video!
The video gives you all the information you need to create your own Launchpad. But you can find additional information in the next steps.
Step 2: Order Your Components!
Here you can find a parts list with example seller:

Step 3: 3D Print the Enclosure!
Here you can find all the design files for the 3D Print. Open them with 123D Design and export them as .stl files.
Step 4: Build the Launchpad!
This step is pretty self explanatory. Just follow the steps from the video and use my reference pictures to build your Launchpad.
Step 5: Program the Arduino Nano!
Here you can find the wiring scheme and the code for the Arduino. Also don't forget to use the given libraries and the MIDI software.
Keyboard library: https://playground.arduino.cc/code/keypad
FastLED library: https://github.com/FastLED/FastLED
